HVAC Maintenance Tips Straight From the Sears Heating & Cooling Team
At Sears Heating & Cooling, our technicians spend every day helping Central Ohio homeowners stay comfortable through scorching summers and freezing winters.
After thousands of service calls, they’ve noticed something:
Most HVAC breakdowns aren’t caused by bad luck.
They’re often caused by small issues that homeowners simply didn’t know to watch for.
So we asked our technicians one simple question:
“If every homeowner could know just a few things about their HVAC system, what would you want them to know?”
Here are their answers.
-
Your HVAC System Will Usually Warn You Before It Breaks
One of the biggest misconceptions is that air conditioners and furnaces simply stop working without warning.
In reality, most systems give homeowners clues long before a complete breakdown.
Watch for:
- Your system running longer than usual
- Uneven temperatures throughout the house
- Higher utility bills
- Strange noises
- New odors
- Weak airflow
Ignoring these signs often turns an inexpensive fix into a major one. If your system starts acting differently, don’t wait until it stops completely. A quick call for air conditioner repair or furnace repair early can save you from an emergency later.
Our advice: If your system starts acting differently, don’t wait until it stops working completely.
-
Your Air Filter Is More Important Than You Think
If there were one simple thing every homeowner could do to extend the life of their HVAC system, it would be changing the air filter regularly.
A clogged filter can:
- Restrict airflow
- Make your system work harder
- Increase energy costs
- Cause your air conditioner to freeze up
- Shorten the life of expensive components
Here’s what many people don’t realize: not every home needs the same filter. A family with pets, allergies, or heavy use may need a different filter and schedule than someone living alone. If you’re unsure, ask your technician, or explore our indoor air quality options for cleaner, healthier air.
-
Bigger Isn’t Always Better
Many homeowners assume that a larger air conditioner will cool their home faster.
Actually, the opposite can happen.
An oversized system may:
- Short cycle on and off
- Leave humidity in the home
- Wear out faster
- Increase energy usage
- Create uneven temperatures
Proper sizing is one of the most important parts of a quality installation. If you’re considering an upgrade, our AC replacement team sizes every system to your home, and our AC buying guide walks you through the decision.
-
Preventative Maintenance Really Does Save Money
We understand.
It’s easy to skip maintenance when your system seems to be working fine.
But regular maintenance allows technicians to catch:
- Weak capacitors
- Worn electrical components
- Refrigerant issues
- Dirty coils
- Drain line problems
before they become emergency service calls.
Think of it like changing the oil in your car, a little today prevents a major repair tomorrow. That’s exactly why we offer our HVAC Service Club, which keeps your system running stronger, longer for one low rate.
-
Don’t Ignore Strange Noises
Your HVAC system shouldn’t become part of the soundtrack of your home.
Grinding.
Buzzing.
Clicking.
Squealing.
Rattling.
Each sound can point to a different issue.
The sooner those noises are investigated, the more likely the repair will be smaller—and less expensive.
-
Your Thermostat Isn’t Always the Problem
Many homeowners assume the thermostat is to blame when temperatures feel off.
Sometimes it is.
But many comfort issues actually come from:
- Airflow restrictions
- Dirty filters
- Refrigerant issues
- Ductwork leaks
- Failing blower motors
- Electrical components
That’s why a complete diagnosis matters, and why upgrading to the right thermostat options is only worth it once the real cause is confirmed.
-
Honest HVAC Companies Don’t Want to Replace Every System
This may surprise you.
Most experienced HVAC technicians take pride in fixing problems—not just replacing equipment.
At Sears Heating & Cooling, we believe in helping homeowners get the most life possible from their investment whenever it makes financial sense.
Sometimes replacement is the right answer, and when it is, our furnace replacement and heat pump options are worth exploring. But sometimes a quality repair provides years of added comfort. Every system, and every homeowner, is different.
-
A Second Opinion Is Never a Bad Idea
Replacing an HVAC system is one of the largest investments you’ll make in your home.
If you’ve been told your system is beyond repair, don’t be afraid to ask questions or seek another opinion.
A reputable company should welcome it, which is why we offer a free second opinion on cracked heat exchangers and compressors so you can feel confident in your decision.
What Our Technicians Want You to Remember Most
If there is one piece of advice our team would give every homeowner, it’s this:
Don’t wait until your HVAC system completely fails before giving it attention.
Small warning signs are your system’s way of asking for help.
Addressing them early can:
- Extend the life of your equipment
- Improve comfort
- Lower utility bills
- Prevent inconvenient breakdowns
- Save you thousands of dollars over the life of your system
